Abstract

A LCD display device and a method for manufacturing the same are disclosed. The LCD display device comprises an array substrate and an aligning substrate that are oppositely arranged, wherein the array substrate comprises a gate line and a data line that are arranged in a crossed manner; and a liquid crystal layer disposed between the array substrate and the aligning substrate. On the side of the array substrate away from the liquid crystal layer, there are provided successively a second polarizer, a light guide plate and a backlight source. A first polarizer is disposed on the side of the aligning substrate away from the liquid crystal layer. Further, the LCD display device also comprises a reflective grid disposed between the array substrate and the light guide plate, wherein the reflective grid is arranged in a shape and position corresponding to at least one of the gate line and data line.

Description

RELATED APPLICATIONSThe present application is the U.S. national phase entry of PCT / CN2017 / 080348 with an International filing date of Apr. 13, 2017, which claims the benefit of Chinese Patent Application No. 201610909356.6, filed on Oct. 19, 2016, the entire disclosure of which is incorporated herein by reference.TECHNICAL FIELDThe present disclosure relates to the field of liquid crystal display technology, and more particular to a liquid crystal display device and a method for manufacturing the same.BACKGROUND ARTAn existing backlight system used for a liquid crystal display device mainly comprises a reflective film, a light guide plate and an optical film, none of which, however, conduct individual optical processing on a single pixel unit. That is to say, light emitted from a backlight source will generally be incident entirely on a liquid crystal display panel, i.e., the backlight may be partially incident on a data line or gate line of an array substrate and thus wasted. The ...
